Already in 1865, his painter friends were desperate to find the good colors of the past. They were no longer making colors themselves in their workshops and, at that time, paints were starting to be offered by a new industry. It was for these painters that Jacques BLOCKX, a wealthy chemist, went to work.
To quote Salvator Dali, writing about Jacques Blockx the founder in "50 secrets of craftmanship": "This man who never painted, will contribute more to the painters of tomorrow than what we will have accomplished, all the modern painters together".
In his book "Compendium" published in 1926 he wrote "In a word, I reject every colour which does not possess the requisite qualities for ensuring complete permanence in artistic painting".
As nice as they can be, we never indeed prepare transient or unstable shades.
About the quality of ingredients used for making pigments he wrote on his order form around 1890: "My products are certified chemically pure. Liquid are sold with my Registred Signature. Our quality is guaranteed!"
More than 100 years later, analyses made by official laboratories worldwide on paintings confirm it.
